GENERAL DESCRIPTION

The DS5002FP secure microprocessor chip is a

secure

version

of

the

DS5001FP

128k

soft

microprocessor chip. In addition to the memory and

I/O enhancements of the DS5001FP, the secure

microprocessor

chip

incorporates

the

most

sophisticated security features available in any

processor. The security features of the DS5002FP

include an array of mechanisms that are designed to

resist all levels of threat, including observation,

analysis, and physical attack. As a result, a massive

effort is required to obtain any information about

memory contents. Furthermore, the “soft” nature of

the DS5002FP allows frequent modification of the

secure information, thereby minimizing the value of

any secure information obtained by such a massive

effort.
